To all whom t may concern.:

Be it known that I, JOHN A.- Komen, a citizen of the United States, and residing at Brooklyn, in the county of Kings and State ot New York, have invented certain new and useful improvements in Lock Devices, of which the following is a speciiication, such as will enable those skilled in the art to which it appertains to make and use the saine. V

rJhis invention relates to lock devices and particularly to devices o't this class desi gned to be used in connection with doors ot various kinds and classes, as for example, the doors of motor vehicles, and the object ot this invention is to provide a lock ot the class whichA with a lew exceptions are composed of sheet metal stampings assembled and secured together in a simple manner. A further object is to provide a lock of the class specified, means whereby the latch bolt may be moved inwardly by door knobs, handles or levers both on the inner and outer side ot' the door and independent of each other in operation; a `further object being; to provide means for locking' the latch bolt operatiiip` means from the outside of the door; a still turther object being to provide means 'for holding the separate latch bolt operating' means in neutral position when the latch bolt is automatically moved inwardly and outwardly in the operawith these and other objects in view the invention consists in a lock device of the class and tor the purpose specified which is constructed and operated as hereinafter described and claimed.

lThe invention is fully disclosed in the tollowing specification, of which the accompanying drawing Jforms a part, in which the separate parts of my improvement are designated by suitable reference characters in eac-h of the views, and in which Figure 1 is a side view ot my improved lock device with part of the construction broken away and in section;

My improved lock device comprises a suitable casing 10 composed of two sheet metal plates 11 and 1:2. The plate 11 is oblong and rectangular in one end thereof with an angularly arranged flange 13 the central portion of which is cut out to torni' an aperture 14 and aportion et' the material of said flange is bent upwardly and inwardly to form a guide member 15 for a latch bolt device 1G. The plate' 12 is fashioned into box-shaped form andthe side and end walls of which are provided at intervals with projecting lugs ll' adapted to be passed through apertures 18 in the plate 11 and the protrudingl riveted to-secure the separate plates .1l and 12 together. rl`he top of the plate 12 .is pio vided in one end portion-thereof with an elongated aperture 19 in which a part of the latchl bolt device operates.

The plates 11 and 12 are provided approximately centrally thereof with two pairs ot' apertures Q() and 21 Aand two roll backs and 23 are mounted within the casing l() and provided with oppositely directed bearings' 24- and which operate respectively in the pairs ot apertures Q0 and 21, as clearly illustrated in lig. Q. The roll back Q3 is proorm and is provided at portions of said lugs are vided with a rectangular aperture 26 adapted to receive a correspoinhngly formed shank 12T ot a knob or handle tor the loch deviceJ and which is )in'eterably mount-ed on the outer side oi the door but which is not shown for the reason that it forms no part of this invention. The roll back is provided with a projecting-1- stud through the plate lil and is inovided with a reduced angular shank .29 on which is mount-Y ed an operating lever 30 held in place by la screw 3l.

rl`he roll back 22 is provided with oppositely extending arms while the roll back 23 is provided with oppositely extending arms 315, as clearly illustrated in. Fig. l of the drawing. rl`he latch bolt device 16 comprises a latch bolt member 34 which is secured to a latch bolt trame 35, which is composed of anfaporoiiinately rectangular sheet of metal, one end of which is bent to form a flange 36 provided with projecting lip 3T, which is countersank in the latch bolt member 34 and secured thereto by weld- 35 is also nro 28 which extends .38 and 39 in connection with which the op- Two ears 40- are stamped from the platel 11 at the opposite sides thereof and bent inwardly to form supports for two guide rods 41 which pass through the fiange 36 of the latch bolt device 16, or the lframe 35 thereof, or upon which said frame is longitudinally movable, and spiral springs 42are mounted on the rods 41 and normally serve to move the latch bolt device intoits operative. or projected position.

Two pairs of spring retaining members 43 and 44 are stamped from the plate 11, one of which is indicated in Fig. 3 of the drawing, and two pairs of spring members 45 and 46 are mounted in the members 43 and 44' respectively, andthe free ends of said spring members operate in connection with the. projecting arms 32 and 33 of the roll backs 22 and 23' respectively and serve to retain said roll backs in their normal position on the inward and outward movement of the latch bolt device in the operation of closingthe door.

Mounted in apertures 47 in the plates 11 and 12 is a stub shaft 48, one end of which passes through the plate 11, and is provided with an opening lever 49'held in place by a nut 50, and secured to t-he shaft 48 within the casing 10 is a pawl 51, the free end portion of which is provided with a V-shaped recess 52 which is adapted to cooperate with one of the arms 33 of the roll back 23, and said pawl is also provided with ay shoulder 53 in connection with which one of the projecting members 39 of the latch bolt device 16 operates as hereinafter described. A spring 54 is mounted within the casing 10 at one side of the pawl 51 and is held in place by the shaft 49 and by a part 55` on said spring which project-s through an aperture 56 in the plate 12. The spring 54 is provided. approximately centrally thereof with a projecting catch 57 which is adapted to operate in connection with two elongated grooves or recesses 58 and 59, this construction is clearly illustrated in Figs. 1, 4, 5 and G of the drawing. The spring 54 serves tov hold the pawl 51` in its operative or inoperative position, said pawl being manipulatedthrough the lever 49 outwardly of the plate 11 and which is located on the inner side of the door. y

The operation of my improved lock device will be readily understood from the foregoing description when taken in connection with the accompanying dra-wing and the following statementp With the pawl 51 in its operative position illustrated in Figs. 1, 4, 5 and G of the drawing, the latch bolt device 16 will not be moved inwardly through the operation of the roll back 22 or i by a handle or knob on the outelaide of the Adoor forthereason vthat the inward movementv of the. latch bolt ldevice 16, or the frame 35 thereof, is limited by the shoulder 53 on the pawl 51 in connection with which one of the as clearly il ustrated in Fig. 1 of the drawrojecting members 39 operates l ing. rlne latch bolt device 16 may be moved it will be seen from the foregoing that when.

the pawl 51 is moved into operative position the door cannot be opened from the outer side but may be opened from the inner side,

In this operation of the lock.

sog

and in which operationthe lock ,pawl 51 is? automatically moved into inoperative position. It will be noted that. the latch bolt device 16, or the frame 35 thereof, is provided with an elongated aperture 6() through which one of the bearings 24-25 of the roll backs 22 "and 23 respectively operate in the inward and outward movement'of the latch bolt device.
